If you were going for less verbose, it could be as easy as… “What do your parents do for a living?” “Parents? I was grown in a Petri dish.” go back to typing

See, this guy understands the assignment.

Yes.

If you want to be regarded as nice and not abrasive/terse, I’ve noticed the best way to respond is with something outlandishly untrue. Nicely declining and honestly declining are exhaustive to cook up especially in the moment. Especially in a professional setting where it kind of matters that you aren’t an asshole to your colleagues. Aim for laughable. The trick is riding the grey line of business casual sarcasm, without saying something inappropriate that makes others uncomfortable. If they believe your dishonesty, you’ve either got a great poker face or you’re talking to an idiot. Either way, it’s an easy fix with a quick “I’m just messing with you bud.” And then bam, conversation over or atleast an easy transition to something else. The smartest people respond with light hearted wit to divert from actually answering things.
